“…Scheme 1(II) briefly shows this fabrication process: NPs are incorporated into the micro/nano-sphere interior as the monomers are polymerized into spheres, mainly by suspension, [65][66][67] dispersion, 68,69 emulsion, [70][71][72] or condensation polymerization. 73,74 Zhang et al 75 (Fig.…”

The study of cancer is of great significance to human survival and development, due to the fact that cancer has become one of the greatest threats to human health. In recent years, the rapid progress of nanoscience and nanotechnology has brought new and bright opportunities to this field. In particular, the applications of quantum dots (QDs) and magnetic nanoparticles (MNPs) have greatly promoted early diagnosis and effective therapy of cancer. In this review, we focus on fluorescent/magnetic micro/nano-spheres based on QDs and/or MNPs (we may call them "nanoparticle-sphere (NP-sphere) composites") from their preparation to their bio-application in cancer research. Firstly, we outline and compare the main four kinds of methods for fabricating NP-sphere composites, including their design principles, operation processes, and characteristics (merits and limitations). The NP-sphere composites successfully inherit the unique fluorescence or magnetic properties of QDs or MNPs. Moreover, compared with the nanoparticles (NPs) alone, the NP-sphere composites show superior properties, which are also discussed in this review. Then, we summarize their recent applications in cancer research from three aspects, that is: separation and enrichment of target tumor cells or biomarkers; cancer diagnosis mainly through medical imaging or tumor biomarker detection; and cancer therapy via targeted drug delivery systems. Finally, we provide some perspectives on the future challenges and development trends of the NP-sphere composites.

“…9 Due to the low solubility in CO 2 , most polymers can only be produced by heterogeneous polymerization, such as dispersion polymerization, 10 precipitation polymerization, [11][12][13] et al To the dispersion polymerization, the stabilizers are usually used to prevent the polymer particles from aggregation. For example, some monomers such as methyl methacrylate (MMA), styrene (St), N-vinylpyrrolidone (NVP), et al have been successfully polymerized by dispersion polymerization using fluorinated [14][15][16] or siloxane-based [17][18][19][20] polymers as the stabilizers. However, these stabilizers have potential environmental pollution problem, or high costs problem, which prohibits its wide application.…”

Utilizing 2,2 0 -azobis(isobutyronitrile) (AIBN) as the initiator, the copolymerization of methyl methacrylate/methacrylate acid is performed by precipitation copolymerization. The effects of pressure, initiation concentration, the methacrylic acid (MA) concentration, and small amount of water are investigated separately. The morphology and molecular weight are analyzed by scanning electron microscopy and gel permeation chromatography, respectively.The results indicates that the concentration of MA or AIBN affects the molecular weight greatly, and the maximum molecular weight reaches 213 kDa. The morphology of samples exhibits a certain degree of agglomeration. Most samples are obtained as free-flowing powder with numerous spherical bulges under a proper polymerization condition.

“…QDs have a high luminescent efficiency [22] and have a wide variety of applications, such as in nanosensors, cosmetic products, nano-electronics, nano-optical devices and energy storage [23,24]. Moreover, ZnO QDs are stable, nontoxic and low cost [23,25], and these and other characteristics allow us to choose them as building treatments to evaluate the real depth penetration of the nanolime treatment.…”
